6.) Write a Little Man program that accepts three values as input and produces the largest of them as its output by filling in the correct mnemonic code in each of the six missing values marked in red below. This program inputs and saves all three numbers. Then it compares the last two. (This saves a LOAD, since the third number is already in the calculator.) The larger of the two is then placed into the calculator, and compared against the remaining input value. (9 points)
00 INP 901 ;input three numbers and save
01 STO 99 399
02 INP 901
03 STO 98 398
04 INP 901
05 STO 97 397
06 ??????? ??? ;subtract number in 98 from that in 97
07 BRP 10 811 ;number in 97 larger
08 LDA 98 598 ;number in 98 larger-restore 98
09 BR 11 611
10 LDA 97 597 ;restore 97
11 ?????? ??? ;store larger of (97, 98) in 96
12 ?????? ??? ;subtract number in 99 from larger
13 BRP 16 816 ;number in 96 larger
14 LDA 99 599 ;number in 99 larger--restore 99
